DevGuru ADO Connection::InfoMessage Event

EVENT: Connection::InfoMessage

InfoMessage pError, adStatus, pConnection

The InfoMessage event can be fired if a warning occurs during a connection operation. It can provide additional information about the warning.

An event is simply a subroutine that can be called automatically after a specific operation has occurred. This subroutine can contain any code that you need to run when the event occurs. The subroutine will only be called if it is included in your code.

There are three parameters that are passed to this event.

The pError parameter is an Error object that contains information about the occurrence of any errors and/or warnings. This parameter requires that the adStatus parameter be set to the adStatusOK constant.

The adStatus parameter is one of the EventStatusEnum constants and defines the status of the event. When a warning occurs, it is set to adStatusOK. To prevent unwanted future firings of this event, set this parameter to adStatusUnwantedEvent before the event returns.

EventStatusEnum Constants

Constant	Value	Description
adStatusCancel	4	Cancels the operation that fired the event
adStatusCantDeny	3	Cannot cancel pending operation
adStatusErrorsOccurred	2	Indicates that warnings and/or errors occurred
adStatusOK	1	The operation that fired the event was successful
adStatusUnwantedEvent	5	The operation that generated the event cannot generate future events

The pConnection parameter is the Connection object that is associated with the warning that fired the event.

Code (Visual Basic):
' Use the WithEvents keyword to designate that events
' can be handled by this Connection object
Dim WithEvents objConn As ADODB.Connection

' Note how the object name, objConn, is incorporated into the event Sub name
Private Sub objConn_InfoMessage( ByVal pError As ADODB.Error, _
   adStatus As ADODB.EventStatusEnum, _
   ByVal pConnection As ADODB.Connection )

' place any code you desire here, for example
If adStatus = adStatusErrorsOccurred Then
   Dim objError As ADODB.Error
   For Each objError in pConnection.Errors
      Debug.Print vbTab objError.Description
   Next
End If

End Sub
